Harry, that Camaro looks like you could make a Hallowe'en mask from it. Scary!
If you use one of the flat base sheets with the Lego you don't need glue. If you are using a plastic body for the buck, fill it with Plasticene and just press it to the floor of the Lego.
Last year for my Studebaker and my Topolino, since they were wood and would float in the resin, I drilled a small hole in the middle of the sheet and screwed the wooden buck in from the bottom. Once the buck is in place, it is easy to gauge how big a Lego box to build around it. After it is set, just unbuild the walls and remove the mould. You may need to trim a bit of silicone to open up the bottom, but that is good as it leaves a bit of an edge to prevent spilling while sloshing. Start with a smaller hole than necessary and then trim outwards until you can get the buck out easily. If the buck will come out, so will the casting.
For small items, other small containers can be used. I used a yogurt cup for a driver mould, and plastic packaging bubbles for moulding wheel insert.
Cheers,
Keith
